Comment(by PaulFertser):
Are you really sure you used a kernel module with the patch and that dmesg
output is really identical?
Please, next time you do any testing,
1. #define DEBUG at the top of ar6000_drv.c (it might change the timing
tough, so if you can't reproduce with it, disable it back, i still hope
it's possible to reproduce it with this option, please try hard).
2. post dmesg
3. post kernel module binary you used (preferably the .o, not .ko file) so
i can locate (instead of guessing) the op that caused NULL pointer
dereference.
Also you might speed up the process a lot if you enable me to reproduce
the issue. Trace all calls to wpa_supplicant and try to reproduce with
wpa_cli (though it might be hard due to timing issues). Alternatively, i
can install nwa myself but i'm unsure i can reproduce your network
conditions so try to minimise the requirements (it's better to have a way
to reproduce it once in 10 times than having to find "an ap with weak
signal etc etc).
